Application.November-21, 1932' Serial No."64 3,789 L i This invention relates baby carriage. In vehicles for babies, it is customary to wheelthe same back and forth for pacifying or quietening the ocparticular object of this movement of the the purpose of cupant, and it is the invention to accomplish this vehicleautomaticallyj Another important object of the inventionvresides in the provision of means ofv this 'nature arrangement of which] is simple in its construction, inexpensive to manufacture, thoroughly eflicient and reliable in use'and operation and otherwisewwell adapted to the purpose for which it is designed." t With the above andnumerous other objects in vview as will appear as the description proceeds, the invention resides in certain novelfeatures of constructiongand in the combination and parts as will be hereinaftermore fully described and claimed; a

Referring to the drawingsjin detail it willbe seen that numeral 5'denotesa casing A pair of rails are constructed of angle-iron and each rail comprises two sections 6 and 7. A plurality of cross bars 8 are disposed between the sections 6-6 and 7.7 and are located at the ends there- I of. The pair of cross bars 8, adjacent each other the sections 7 may are hingedly connected together as at 9 so that befoldedun'der the sections 6 and the casing 5' in use.,fUnder the casing and under the rails .are suitable feet indicated by the numerals 10. Each cross member 8 comprises an elongated section a and a relatively short section b under one end thereof. The section a has a plurality of openings 12 so that a through one of them as indicated at 14 to engage of courseQis attached to one rail while the secthe carriage may ride in an opening in the section b; The section b,

tionfa is attached to theother rail, By proper ,adjustment, therefore, the rails may be disposed different distances apart depending upon the width of the baby carriage'so that the wheels of nism including a connecting rod 15 which is to be oscillated by the mechanism and'a plate 16 is fixed to the bottom of the body of the carriage and: has a pairof spaced to means for oscillating a 23' by a belt 24 over a pulley 'able belt tightening means 30 the carriage 'or the like. i I It is thoughtthat the construction, operation,

It will be apparent that changes in the details of construction-and in: the'combination' and arran'gement of parts may be resorted to without its advantages. H
